Description
Technical field
The present invention relates to transfusion device technical field, especially a kind of medical Transfusion device with anti-blood back function.
Background technology
Transfusion device is a kind of medicine equipment of transfusion, and traditional infusion method is that the liquid in bottle is suspended on height
Place, makes liquid be flowed into by infusion rubber tubing intravenous using the effect of gravity, and the size of flow is by the clip that is placed on leather hose
To carry out manual adjustment, after the decoction in bottle terminates, such as medical personnel pull out syringe needle not in time, because the diffusion of liquid is made
With the blood of human body can be back in the woven hose of transfusion device, cause the bacterium infection even various malpractices such as septicaemia, danger
The personal safety of evil patient.
The content of the invention
The technical problem to be solved in the present invention is：The problem of in order to solve transfusion device blood back, now offer one kind, which has, prevents back
The medical Transfusion device of blood function.
The technical solution adopted for the present invention to solve the technical problems is：A kind of medical infusion with anti-blood back function
Device, including puncture outfit, dropping funnel, flow regulator, intravenous infusion needle and conduit, are connected between the puncture outfit and dropping funnel by conduit
Connect, in addition to thin slice and pole, the puncture outfit is made up of inner cylinder and outer barrel, and the inner cylinder is connected with the conduit, it is described outer
The top of cylinder is angle, and the top of the inner cylinder is flat mouth, and one end of the pole is fixedly connected with the thin slice, the pole
In the inner cylinder of other end insertion puncture outfit, the flat mouth of inner cylinder can be completely covered in the thin slice, and the angle outer barrel of puncture outfit is used for wearing
Bottle stopper is pierced, pole is very long close with the height of infusion bottle, and pole is inserted in the inner cylinder of puncture outfit, and pole can ensure thin slice defeated
Liquid bottle in will not disorderly float, and transfusion terminate after can fall in the flat mouth of the inner cylinder of puncture outfit, when there is liquid in infusion bottle, thin slice
It can float on a liquid, so that liquid can flow out from the flat mouth of inner cylinder, as liquid is slowly reduced, thin slice can also follow decline,
When liquid flows to end, thin slice can block the flat mouth of inner cylinder, so that there will be no the generation of the thing of blood back.
In order that thin slice provides enough floatage energies and drives pole preferably to float further, the centre of the thin slice
Position is provided with raised bubble.
In order that thin slice is preferably fitted, further, the diameter of the raised bubble is more than the flat mouth of the inner cylinder of puncture outfit
The diameter of the flat mouth of inner cylinder.
Preferably, the raised bubble is ball-type.
The beneficial effects of the invention are as follows：The medical Transfusion device with anti-blood back function of the present invention is simple in construction, and effect is bright
Aobvious, by inserting the thin slice with raised bubble in the inner cylinder of puncture outfit, thin slice can decline as liquid level declines, to realize
Transfusion terminates rear thin slice and blocks the flat mouth of inner cylinder, effectively solves the problem of blood flows back.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the implementation schematic diagram of the present invention；
In figure：1st, raised bubble, 2, outer barrel, 3, infusion bottle, 4, thin slice, 5, inner cylinder, 6, pole.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
Embodiment 1
A kind of medical Transfusion device with anti-blood back function as shown in Figure 1, including puncture outfit, dropping funnel, flow regulator,
Intravenous infusion needle and conduit, are connected between puncture outfit and dropping funnel by conduit, in addition to thin slice 4 and pole 6, and puncture outfit is by inner cylinder
5 and outer barrel 2 constitute, inner cylinder 5 is connected with conduit, and the top of outer barrel 2 is angle, and the top of inner cylinder 5 is flat mouth, one end of pole 6
It is fixedly connected with thin slice 4, in the inner cylinder 5 of the other end of pole 6 insertion puncture outfit, the flat mouth of inner cylinder 5 can be completely covered in thin slice 4.
Embodiment 2
The difference of embodiment 2 as shown in Figure 1 and embodiment 1 is that the middle part of thin slice 4 is provided with raised bubble 1, raised
Bubble 1 is ball-type, and the diameter of raised bubble 1 is more than the diameter of the flat mouth of inner cylinder 5.
Operation principle：
When having liquid in infusion bottle 3, thin slice 4 can be suspended on liquid, and thin slice 4 is located at the top of pole 6, and pole 6 is very
Length is close with the height of infusion bottle 3, and pole 6 is inserted in the inner cylinder 5 of puncture outfit, and pole 6 can ensure thin slice 4 in infusion bottle 3
Will not disorderly float, and transfusion terminate after can fall in the flat mouth of the inner cylinder 5 of puncture outfit, start transfusion when, puncture bottle stopper so that liquid
It can be flowed out from the flat mouth of inner cylinder 5, as liquid is slowly reduced, thin slice 4 can also follow decline, and when liquid flows to end, thin slice 4 can handle
The flat mouth of inner cylinder 5 is blocked, and the raised bubble 1 on thin slice 4 can fit the flat mouth of inner cylinder 5 well.
Using the above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
